Operation principle of the present invention is:
By air inlet pipe 110, extraneous source of the gas is connected with the air admission hole 122 breathing separator 120, outside air is first entered by inlet manifold 126 and breathes separator 120, through filter screen, adsorption for sterilization district, ultraviolet sterilization district and electrostatic precipitation district carry out four purifications to air successively, air after purification enters the house steward 125a that gives vent to anger of gas flow distribution device 125, be divided into some roads through distributor 125b again and enter out gas branch pipe 125c, it is the continual and steady of maintenance flow that flow control valve 125d controls every road gas flow gone out in gas branch pipe 125c, finally, gas exports escape pipe 130 to through venthole 123, deliver the gas to protective garment 140 inside by escape pipe 130 to breathe for operating personnel, breathe the exhaust apparatus 145 of waste gas in protective garment 140 produced to discharge.In this process, the first pressure sensor 127b Real-Time Monitoring breathes the pressure size in separator 120, when pressure is excessive, opens relief valve 127a pressure release, to reduce the gas pressure breathed in separator 120, ensures the stable of output gas flow of gas.
Second pressure sensor 135f detects valve body 134a internal pressure in real time, when pressure normal constant, escape pipe 130 normally works, gas exports through escape pipe 130 and enters protective garment 140 inside, the thrust imposing on valve gap 134b due to gas is greater than the active force of permanent magnet 135e, valve gap 134b and valve body 134a disengages, it is inner that gas enters escape pipe 130 by the gap between valve gap 134b and valve body 134a, and enter protective garment 140 inside for operating personnel's breathing by escape pipe 130 of the present invention, when detecting that pressure declines suddenly, the thrust that gas imposes on valve gap 134b die-offs or disappears, the magnetic force sweeping action pull bar 135b of permanent magnet 135e rotates, action pull bar 135b drives wind wheel 135a to rotate, wind wheel 135a drives first connecting rod 135c to rotate, second connecting rod 135d is pulled after first connecting rod 135c is stressed, valve gap 134b is pulled against inlet end after second connecting rod 135d is stressed, valve gap 134b is made to move to close valve body 134a end against airintake direction, thus realize escape pipe 130 self-locking, simultaneously, alarm gives the alarm, notify that operating personnel's escape pipe 130 has loosened or departed from and breathe separator 120, to reduce the potential safety hazard that operating personnel is poisoning or suffocate.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
